For some time we thought that we were seeing just a single white species from the Gymnodorididae family. Then we realised that they are not all the same… and then we found a black coloured one too…
Again these nudibranch are only encountered at our local dive sites – no sightings when diving beyond Koh Phangan.

    Gymnodoris alba

    Previously confused by us with another small, white Gymnodorid Nudibranch - G. citrina, listed below

    Gymnodoris citrina

    We have spotted this particular small, carnivorous Gymnodorid only once, it seems.

    Gymnodoris cf nigricolor

    Very small, super active, and totally black in appearance.
